Vitamins and Minerals Essential for Preventing Hair Loss

Hair shedding of 50‑100 strands daily is normal; persistent loss above this indicates hair‑loss conditions. Scientific sources note that deficiencies in zinc, copper, iron, vitamin B7 (biotin) and imbalances of vitamin A can trigger or worsen hair shedding. Zinc and copper deficiencies weaken hair, but the two minerals should not be taken together because they compete for absorption; timing doses separately can improve utilization. Iron supports hair‑follicle health, while biotin contributes to strong hair and skin. Antioxidant vitamins such as E, B2 (riboflavin) and C also aid hair health by reducing oxidative stress. Diagnosis typically involves a scalp examination and a hair‑wash test, where shed hairs are collected and analyzed. The hair growth cycle comprises a growth phase (2‑6 years), a transition phase (about three weeks), and a resting phase (2‑3 months), after which the hair is shed and a new strand begins to grow. Supplementation should only be undertaken after medical assessment and blood‑test confirmation of any deficiencies, and always under a physician’s guidance.

These guidelines emphasize that while dietary nutrients play a vital role in hair health, they are one factor among many, including hormonal changes, medication, scalp disorders, stress, and genetic predisposition.
